i have web service proxy. on proxy there method takes 2 custom types. when call web service, soap message generated. in scenario, capture soap message manually (using fiddler). able de-serialize string containing soap message (that read manually created file) instances of 2 original types. i know easy enough xml dom, xpath, , xml serialization 2 types. i'm doing this, though 2 separate files. i'd combine them, , avoid manual formatting of captured soap message. is there more automatic way leverage existing soap infrastructure deserialization? i'd write serialization code once , expect work. it appears .net framework doesn't expose in easy use manner. custom code writes/reads data (in soaphttpclientprotocol , soapserverprotocol ) not directly exposed user. you can use code @ least guts of request map correctly: xmltypemapping xmltypemapping = new soapreflectionimporter() .importtypemapping(typeof(t)); var xmlserializer = new xmlserializ...

we using ef code first app fabric cache on windows azure (although, think question more generic since using asp.net caching provider). there easy way enable caching of dbset objects? our db small , not updated frequently, ideally cache entire database in memory, , use ttl expiry refresh object sets. advise experience caching using ef code first great. don't that . if want cache data, extract them separate lists , cache them separately. caching dbset means caching dbcontext promote anity-pattern in entity framework. problems identity map , unit of work described in linked answer. problem there no real refresh. if want refresh data must dispose context , create new one. context not thread safe sharing among multiple requests can cause unexpected results.

i've been reading bit on how people internationalization. seems common consensus save strings in separate file (usually xml) , load when necessary. i'm wondering why not store strings in database instead? isn't better way? btw nature of app website app. the important thing store string tables outside of compilation units incorporating updated translations not require rebuild. allows new or updated translations incorporated @ later point without hassle. of course, string tables stored anywhere. if want put them in database, knock out. long application can reach them , translation staff know how deliver them right place, doesn't make difference.

in wordpress - how assign class custom fields? attempting target multiple custom fields custom css, seem unable give them separate classes. this not best solution, worth shot, i'd loop per field get_posts this: $args = array( 'meta_key' => 'custom_attribute', 'meta_value' => 'value1', ); $value1 = get_posts($args); $args = array( 'meta_key' => 'custom_attribute', 'meta_value' => 'value2', ); $value2 = get_posts($args); so give 2 arrays, each 1 pulling different posts, can foreach going through each array (value1 , value2) , adding classes needed.

i'm using delayed_job 2.1.4 collectiveidea, , seems perform method never called though jobs processed , removed queue. missing something? i'm using rails 3.0.5 on heroku in controller: delayed::job.enqueue facebookjob.new in job class: class facebookjob def initialize end def perform fb_auths = authentication.where(:provider => 'facebook') fb_auths.each |auth| checkins = fbgraph::user.new('me', :access_token => uri.encode(auth.token)).checkins if checkins != nil checkins.each |checkin| [...] end end end end end (the whole code: https://gist.github.com/966509 ) i had same problem, answer helped me: delayed_job not executing perform method emptying job queue

i have 2 data.frames, 1 characters , other 1 characters , values. df1 = data.frame(x=c('a', 'b', 'c', 'd', 'e')) df2 = data.frame(x=c('a', 'b', 'c'),y = c(0,1,0)) merge(df1, df2) x y 1 0 2 b 1 3 c 0 i want merge df1 , df2. characters a, b , c merged , have 0, 1, 0 d , e has nothing. want d , e in merge table, 0 0 condition. every missing row @ df2 data.frame, 0 must placed in df1 table, like: x y 1 0 2 b 1 3 c 0 4 d 0 5 e 0 take @ page merge. all parameter lets specify different types of merges. here want set all = true . make merge return na values don't match, can update 0 is.na() : zz <- merge(df1, df2, = true) zz[is.na(zz)] <- 0 > zz x y 1 0 2 b 1 3 c 0 4 d 0 5 e 0

i wondering if there anyway of using jsp in <c:if> statement. e.g. <c:if test="${ param.variable1 == 'add' <% jsp variable clause %>}"> so want jsp variable checked against well. any suggestions? have tried ignorantly sticking in clause, did not work. thanks so want evaluate scriptlet variable in el? store request attribute. <% string var = "some"; request.setattribute("var", var); %> <c:if test="${param.variable1 == 'add' && var == 'some'}"> however, makes no sense. should avoid scriptlets altogether , use jstl/el prepare variable. if make functional requirement more clear, e.g. "how do (insert scriptlet code snippet) using jstl/el?", we'll able suggest right approach. for example, use <c:set> set variable in el scope. <c:set var="var" value="some" scope="request" /> see also: ou...

possible duplicate: how transfer java array javascript array using jsp? after googling still not able pass array .jsp file js file. can me out? in .jsp file have array , wan call function in .js file accepts array. how call function? by passing array .jsp js file guess mean javascript script needs "call" script return jsp file. , script contains function returns array? if have looked @ returning json jsp?

imaging scripting code: procedure a; begin calltodelphi; end; procedure b; begin // end; i have exposed procedure "calltodelphi" script. when called, i'm script in delphi code. want call script procedure "b" delphi code. think must hidden in idwsprogramexecution-context. didn't found yet. i'm looking that: procedure calltodelphi; begin exec.invoke('b', []); // exec idwsprogramexecution end; is somehow possible? what you're looking iinfo interface can used as exec.info.func['b'].call([]) there more samples in http://code.google.com/p/dwscript/wiki/firststeps (scroll down functions), , usage code in unit tests (udwsunittests notably, see callfunc method). the iinfo serves delphi-side primary way query rtti, invoke functions, get/set variables directly, instantiate script-side objects, etc. of sample code in unit tests though.

i have class: model , many functions, such draw() , rotate() etc. now have class called cube want able work same way model. i have in cube class constructor: model m3d = new model(); m3d.build(obj); so want able in class call like: mcube.draw(); and m3d perform draw() . ok. in class call: class cube extends model {...} then can do: cube mcube = new cube(); mcube.build(obj); mcube.draw();

which mvc diagram correct? each have different arrows... diagram 1 diagram 2 http://blog.stannard.net.au/blog/media/simple-mvc-framework/mvc.gif diagram 3 diagram 4 http://java.sun.com/blueprints/patterns/images/mvc-structure-generic.gif diagram 5 http://www.shopno-dinga.com/dustbin/mvc.png they are. mvc vague pattern. my view on mvc : controller object has collection of models , has methods viewing , editing models. talks models , returns instances of views models applied on them. view has definition of model attached , set of functionality display specific model. model encapsulates data. has methods returning state , changing state. //controller import views class controller private models //view import model class view //model class model a model doesn't need know view / controller. view needs know definition of model. controller needs own models , needs know definitions of views. you can couple them more tightly, opt...

i have winforms project want open wpf window wpf user control project. when create instance of wpf window , call show(), bootstrapper isn't loaded. in windows application, it's located in app.xaml, user control project doesn't have this. can do? thanks! the thing accomplished having bootstrapper in app.xaml's resources instantiation of bootstrapper , keeping reference isn't garbage-collected. try making instantiate this: public class someclass { static bootstrapper _bs = new bootstrapper(); ... } that make sure it's initialized part of static construction, happens sometime before can create instance of someclass . may have experiment see whether should happen in usercontrol or in window.

see picture above. each navigation tab needs have 2 pixels separation on either side , line header image on edges. now introduce 5th navigation tab (and possibly 6th). possible code in way stick 5th or 6th tab in there , resize appropriately lists or tables or other solution? still keeping 2 pixels separation , lining edges exactly? wasn't sure if possible or have define widths each time each tab based on math involved line correctly flush edges. i think best way emulate table behavior css. can use list, , still table behavior. ul { display:table; } li { display:table-cell; } here demo displaying css , proper markup. here's demo of how looks actual table. i'm not on ie<8 support css, may aware of. update : confirmed: not supported on ie6 or 7 natively. may stuck tables or hard-coded widths if want support browsers. there may javascript fix support these display values i'm not aware of it. edit : realized demos sloppy, made addres...

i need escape % characters in string entered user - replacing them [%] unless @ start or end of string. for example %foo%foo[%]foo% should become %foo[%]foo[%]foo% . whitespace isn't concern: escaping mid-string percent signs. a regular expression of [^[]%[^\]] match mid-string percentages, adjacent characters (so o%f in example). is there reasonable regular expression match mid-string non-escaped percentage characters? i wondering if non-regex solution preferable, such as iterating through characters in string, , building replacement string percentages escaped const string test = "%foo%foo[%]foo%"; stringbuilder escaped = new stringbuilder(); escaped.append(test[0]); (int = 1; < test.length - 1; i++) { if (test[i] != '%' || (test[i - 1] == '[' && test[i] == '%' && test[i + 1] == ']')) { escaped.append(test[i]); } else { escaped.append("[%]"); } } ...
